The i7-8700K is Intel’s latest, top of the range, 8th generation Coffee Lake processor. Like Kaby Lake and Sky Lake before that, Coffee Lake is based on Intel’s 14nm architecture which has been slightly optimized on each iteration. Following AMD’s modus operandi, Intel has upped the cores and threads across the range of their CPUs. In previous generations, a 6-core processor would have been a high-end desk-top (HEDT) processor, however the i7-8700K is the first Intel CPU with 6 cores and 12 threads to be classified (and priced) as a mainstream consumer processor. Specifically, the i7-8700K features a base clock speed of 3.7 GHz which boosts to 4.7 GHz (4.5 GHz for the previous generation i7-7700k), 12MB of smart (L3) cache and 2 channels of DDR4 RAM. The majority of the performance improvements over the 7th generation stem from the higher core count which results in a 50% increase in multi-core speed between the i7-7700k and i7-8700k. A new motherboard will need to be factored into the budget when upgrading to the 8700K as it requires a new Intel Z370 chipset which has supposedly been designed to better deliver power to CPUs with a greater number of cores. Also available in this latest release of CPUs is the 6 core 6 thread i5-8600k which is a more rational option (around $100 cheaper) for the vast majority of users that don’t require hyper-threading. Sandy bridge owners can finally justify an upgrade but with the next iteration of AMD's Zen architecture just around the corner the CPU market will be a lot faster moving now that Intel, once again, has to compete. [Sep '17 CPUPro]

Intel’s tenth gen, six-core i5-10600K is one of the fastest consumer CPUs currently available. Out of the box, its maximum all core frequency is 4.5 GHz, but a simple overclock allows all 12 threads to hit 5.0 GHz. Although a new Z490 (LGA1200) motherboard is required, Intel have indicated that LGA1200 will remain compatible with Rocket Lake CPUs which are due later this year. The eight-core Ryzen 3700X currently competes in the 10600K’s price bracket. CPU based encoding is akin to using hair clippers on a lawn but If dedicated hardware such as NVENC or QuickSync is not an option, the 3700X can outperform the 10600K in encoding workloads such as UserBenchmark 64-core, Cinebench, Blender-CPU and Handbrake-CPU. Meanwhile, the 10600K is better for almost everything else. Currently, the real problem with the 10600K, and much of the Comet Lake line up, is availability. Whilst there was a paper launch in Q2 2020, at the time of writing, the 10600K is still largely unavailable for purchase. In order to achieve better value for money, without compromising on gaming performance, it is necessary to consider the older generation 9600K which is 26% cheaper and offers similar gaming performance. [Jun '20 CPUPro]
